A 6cm diameter horizontal pipe gradually narrows to 4cm.
Rom4ik [11]

Answer:Q=0.5612 m^3/s

Explanation:

Given

diameter of pipe(d_1)=6 cm

diameter of pipe(d_2)=4 cm

P_1=32 kPa

P_2=24 kPa

A_1=\frac{\pi }{4}6^2=9\pi cm^2

A_2=\frac{\pi }{4}4^2=4\pi cm^2

v_1=\frac{Q}{A_1}

Applying bernoulli's equation

\frac{P_1}{\rho g}+\frac{v^2_1}{2g}+z_1=\frac{P_2}{\rho g}+\frac{v^2_2}{2g}+z_2

\frac{P_1}{\rho g}+\frac{\frac{Q^2}{A_1^2}}{2g}+z_1=\frac{P_2}{\rho g}+\frac{\frac{Q^2}{A_2^2}}{2g}+z_2

since z_1=z_2

\frac{32\times 10^3}{10^3\times 9.81}+\frac{Q^2}{2A_1^2g}=\frac{24\times 10^3}{10^3\times 9.81}+\frac{Q^2}{2A_2^2g}

Q^2=\frac{8\times 2\times 81\pi ^2\times 16\pi ^2\times 10^{-4}}{65\pi ^2}

Q^2=3149.3722\times 10^{-4}

Q=\sqrt{3149.3722\times 10^{-4}}

Q=0.5612 m^3/s

A 1500-W heater is connected to a 120-V line for 2.0 hours. How much heat energy is produced?
weeeeeb [17]
<span>A joule is equal to one watt per second and so we must find out how many seconds are in two hours. A shortcut you can use is remove the zeros and multiplying the remaining numbers before adding the the zeros back to the total of your result 6 x 6 x 2 = 72 and thus 60 x 60 x 2 = 7200 72 x 15 = 1080 and thus 7200 x 1500 = 10800000 joules one mega joule equals one million joules So we can simplify things and say 10.8 MJ</span>
